2 Claims. (Cl. 173-259) 1 2 My invention relates to improvements in batshown in Figure 2 with the top of the collar tery terminals.

The object of the present invention is to provide a terminal structure which can be mainly constructed of a shell made of relatively hard metal, or non-metallic substance, which is capable of being suitably coated to resist sulphate deposit or to be immune to such deposit, which shell is filled with lead or suitable alloy to form the contact area and to unite the cable to the terminal. A further object is to provide a terminal structure which can be applied to, or removed from, the battery post with a simple tool, the application or removal of the structure being done without exerting any strain, either rotational, endwise or compressive, below the taper of the terminal post of said battery. A still further object is to devise such a terminal structure that sulphate deposit on any of its parts will not increase the effort required to remove said structure from the terminal post.

Referring to the drawings- Fig. 1 is a plan view of the invention.

Fig. 2 is a longitudinal sectional view taken on the line 2-2 of Figure 1, showing, the parts about to be secured in position.

Fig. 3 is a part elevational and part sectional view of the device when fitting it to a battery terminal post.

Fig. 4 is a part elevational and part sectional view of the device when removing it from a battery terminal post.

In the drawings like characters of reference indicate corresponding parts in each figure.

The numeral I indicates generally a cable connector which is preferably made as a mould 2 in the form of a flat annular casing having a cylindrical side wall I and top and bottom flanges 5 and Ii respectively. Extendingradially from the wall I is a tubular sleeve I open at its outer end to receive th end of a battery cable 8.

When the cable 8 is inserted into the sleeve I, the casing and the spaces suroundlng the wires of the cable are filled with lead, leaving a central tapered opening having a downwardly converging peripheral wall 9, thus completing the cable connector I in its preferred form. The normally exposed surfaces of the connector I may be coated with a plastic or vitrious material to prevent the deposit of sulphate thereon.

A split collar of lead or other appropriate metal I2 which is tapered on its outer periphery to conform to the tapered wall 8 of the cable connector is provided. This collar I2 has an inner peripheral wall I4 which is tapered to conform to the taper of the post I5 extending upwards through the top wall I6 of a battery II.

In applying the cable connector I to the battery post IS, a clamp 20', see Figures 3 and 4, having a bale 2| with spaced legs 22 and inturned clips 23 and a clamping screw 24 is used. The collar I2 is first pressed lightly into the opening of the cable connector I until it adheres to the tapered peripheral wall 8 of said opening, the collar with the connector loosely attached is then slipped onto the post It, where it assumes a position as approximately level with the top of the post. A plate 26, of greater diameter than the top of the post I5 is laid over the collar and the clamp screw 24 applied thereon, the clips 23 of the clamp 20 being hooked under the mold or casing 2. As the screw 24 is tightened, the connector I is drawn upon the outer wall of the collar I2, thus binding it to the collar and the collar to the post, with the several parts coming to rest substantially in the position shown in Figure 3, the clamp is then removed.

When it becomes necessary to remove the connector from the post, the clamp is again used, but without the plate 26. In this case the force of the clamp screw is applied directly to the top of the post, so that the upward thrust of the clips 23 will draw the cable conector I and the collar I2 as a unit upwardly along the tapered wall of the post, as shown in Figure 4. When these parts are removed, they can be separated, if necessary, before refitting, but this is not necessary, as proceeding again as previously described with the plate 26 in position, the collar can again be contracted onto the post.

What I claim as my invention is:

1. A battery terminal comprising an annual casing having a cable socket in communication with said casing, said casing having a peripheral wall and upper and lower flanges, a body of soft metal within the casing adapted to form an electrical contact with a battery cable, said body of metal having a tapered opening concentric with the upper and lower flanges, and a split collar adapted to fit onto a battery post and into the tapered opening in the body of soft metal, the taper of the outer and inner peripheral walls of said collar being opposed to each other and of substantially similar angles.

2. A battery terminal comprising an annular casing having a cable socket in communication with said casing, said casing having a peripheral wall, a body of soft metal within the casing adapted to form an electrical contact with a battery cable, said body of metal having a tapered opening concentric with the casing, and a split collar adapted to fit onto a battery post and into the tapered opening in the body of soft metal, the taper of the outer and inner peripheral walls of said collar being opposed to each other and of substantially similar angles.
